With the Kemper's extraordinary capbilities, it's easy to drift into FOMO - fear of missing out. As in, "there's probably an EVEN BETTER rig among the thousands and thousands out there." Ditto all the effects.
I use mine for "live" work only, no recording. That means practice, band rehearsal, and gigs. I started out by first thinking of what small number of amps I would go get if money were no object, based on the stuff I play. That ended up being a couple Marshalls (plexi, 800, etc.), a fender deluxe reverb, a vox, and some Dr. Z's (since I own several of those). Then I looked at a limited number of profiler company's offerings based on reviews I've read. Bought a few based on reviews and online samples (ended up with Michael Britt and Rick Beato being my two faves).
Then I created performances with those amps - focusing on a very good clean tone, an "edge of breakup" tone, a very crunchy tone, and then a couple lead tones. I did this for my single coil guitars and separate ones for humbuckers.
Then I added effects as indicated above -- only added what I needed, not any "gee whiz" stuff. So locked in a wah for all, some compression, reverb, delay, chorus for the clean tones, some boost and delay, and the odd phaser, for the lead tones. With that, I've ended up with 4 or 5 performances that I can easily navigate depending on the guitar and what I'm playing, and it covers 99% of everything I need to do. Then I can focus on practice.
From time to time, I sit down and just experiment, but that's when I'm specifically in the mood to see what the Kemper can do. I don't let that interfere with practice. There I play with new rigs, new effects, etc. Mainly to to learn more about how the Kemper works and what i can do.
And I backup like crazy via Rig Manager so I don't lose anything or can restore if I accidentally overwrite something (which has happened too many times).
Any of these devices can be 1,000 mile deep rabbit holes. You have to approach them with a clear idea of what you want, and push back against that FOMO feeling. Oh, and I'm 100% in the camp the believes most of your tone is in your fingers -- there's no rig on earth that will make me sound like EVH no matter how good I am. I will always sound like me. So my expectations of profiles is somewhat tempered - I look for them to sound like the amp, not the artist, because I'm not going to sound the artist no matter what.
